RETURN CQNVEYER FOR MANGLES.

T 0 all "whom it may concern:

Be it known that 1, WILLIAM HARPER, a citizen of the United States, residing at Kansas City, in the county of Jackson and Stateof Missouri, have invented certain new and useful Improvements in Return Conveyers for Mangles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to laundering machines and particularly to a mangle.

Usually the goods to be ironed are fed from one side of the mangle and are delivered at the other. It frequently happens that the goods are not sutficiently ironed when they pass through the machine so it is necessary to put them through the machine again, in some instances, two or three times.

My invention contemplates the utilization of a return conveyer or belt which can be so associated with the mangle that it will be conveniently accessible to receive the goods to be returned so that they will pass back to the original point to be again put through the machine. This saves time and the necessity of carrying the goods around the ends of the machine when they have not been sufficiently ironed during the first ironing process.

The invention will be clearly apparent by reference to the following description in connection with the accompanying drawings, in which- Fig. 1 is a general perspective outline of a mangle of known construction to which my invention is applied.

Fig. 2 is a diagrammatic cross sectional view through the mangle to which my invention is applied.

Fig. 8 is an elevational view of a belt tightener, and

Fig. 4 is a cross sectional view through the belt tightener shaft and the roll about which the belt passes.

Referring now to the drawings by numerals of reference:

1 designates the main cylinder of a con ventional form of mangle, over the top of which is a suitable number of rollers; in the present instance, five, designated 2, 3, 4, 5 and 6. 7 is a feed belt, by means of which the goods may be fed between the cylinder 1 and the arcuate set of rollers above it, the goods passing between the periphery of the cylinder 1 and the rollers 2, 8, 4, 5 and 6, where they may be deposited upon the belt 8, to be discharged upon the table 9. All this is old and well known construction.

Mounted upon the side frames of the mangle are brackets 10 and 11, each of which carries a sliding member 12, having upstanding ends 18 and 14, in which are mounted a screw 15, adapted to be turned through the medium of the hand wheel 16. The screw in each instance passes through a block 17 in which one end of a shaft 18 is mounted, it being understood that there are two blocks, one to receive each end of the shaft 18. Therefore, when the hand Wheel 16 is turned to operate the screw, the block 17 can be adjusted toward and away from the cylinder 1.

The shaft 18 is provided intermediate its ends with a pair of ball races 19 and 20, spaced apart and about which is mounted a roller 21, over which an endless belt 22 passes, the endless belt extending over the rollers 2, 3, 4, 5 and 6 and beneath them over the upper portion of the cylinder 1. Therefore, the belt will be frictionally driven when the device is in operation so that the upper surface thereof will always be moving in a forward direction or toward the front of the machine, it being understood that a table 23 is located at the front of the machine.

The belt 22 may consist of any suitable material but in the present instance I recommend sponge cloth, although the belt need not be limited to any particular material.

From the foregoing it will be apparent that the brackets 10 and 11 may be con veniently attached to the frame of the mangle and that the members 12, there being one for each bracket 10, can be adjusted thereon through the medium of the bolts 24 and 25 or, if no adjustment is desired, the members 12 can be secured directly to the brackets 10.

Since the shaft 18 is mounted in the blocks 17, one near each end of the machine, the shaft 18 can be moved back and forth to provide the necessary tension for the belt 22 to compensate for slack and the like and to insure the proper operation of the belt 22 so that its effective surface will move toward the back of the machine when the machine is in operation.-

As the goods come from the machine, the inspectors 0r operatives will note that some of them are not properly ironed, so it will be only necessary to throw them onto the belt 22 so that they will be conveyed tothe back of the machine to be replaced upon the endless belt 7 passing around the rollers 26 and 27 to again be subjected to the action of the mangle. This will facilitate the ironing operation and provide a convenient means for returning unfinished goods to the entrance side of the mangle to again be placed upon the belt 7 or its equivalent.

What I claim and desire to secure by Letters Patent is:

In combination, the main roller or drum roller and ironing rolls over which the end-- less belt runs so that the ironing rolls may keep the belt in frictional contact with the drum, the endless belt being of less Width than the drum and the ironing rolls.

In testimony whereof I affix my signature.

WILLIAM HARPER.
